In this study thirty cases of thoracolumbar spine injuries with neurological involvement were treated by posterior spinal fixation using the variable screw placement system (VSP system) introduced by Dr. Arthur Steffe. Thirty patients with similar injuries were taken as controls. Study was done regarding the neurological recovery and incidence of complications. Most of the patients (60%) were in the age group of 26-35 years with mean age of 29.3 years. Commonest mode (60%) of injury was a fall from height, leading to Flexion compression type of injury. None of the patients in the operated group had any neurological deterioration as compared to the control group where two patients were deteriorated. Forty percent cases showed an improvement in neurological status in the operated group with the percentage going up to 53.3% in the patients with incomplete neurological damage. This compared significantly with the control group where only twenty percent of the patients showed neurological recovery. In the operated group 20%, of the patients developed Bed Sores, 12.3% developed urinary tract infection and respiratory tract infection each. In contrast, with the control group all these complications were insignificantly higher percentage e.g. Bed sores in 66%, urinary tract infection 46.6% and respiratory tract infection in 33.3%. Screw loosening and misplacement of screwswere noted in 20% cases which may be controlled by using the image intensifier. Post-operatively two patients developed deep infection where implant had to be removed.
